Angelica Dass is recording and cataloguing human skin tones and displaying them against Pantone shades in an effort to 'collect' them all:
The goal of the project is to record and catalog every possible human skin tone for posterity. Dass uses an 11 x 11 pixel of each model’s face and assigns the skin tone a Pantone value from it. She then creates a background in that very shade and shoots the subject in front of it. Considering that Pantone is the leading authority on color in the world, the result is a clinical chromatic inventory/art work that shows off how truly colorful we humans can be.
